### **Descriptions:**
The IRS2128 is a dual-channel driver designed for high-speed switching applications, including motor drives, inverters, and power supplies. It features independent high-side and low-side gate drive channels, allowing for flexible half-bridge configurations. The driver includes undervoltage lockout (UVLO) protection to prevent malfunction during low-voltage conditions.
### **Features:**
- **High-Speed Switching:** Optimized for fast MOSFET/IGBT switching.
- **Bootstrap Operation:** Supports high-side floating supply up to 600V.
- **CMOS Schmitt-Triggered Inputs:** Ensures noise immunity.
- **Matched Propagation Delays:** Reduces deadtime distortion.
- **Low Di/dt Gate Drive:** Minimizes EMI.
- **Integrated Deadtime:** Prevents shoot-through in half-bridge applications.
